The world is expanding at an accelerated rate and this expanding upon is an effect of dark energy . We do n’t acknowledge what dingy Energy Department is and there are unlike account for it , but scientists distrust they can reign out some of the models by using gravitative waves .
Dr Lucas Lombriser and Dr Nelson Lima from the University of Edinburgh have looked at Einstein ’s possibility of general relativity and alternatives of it known as modified gravity . According to their subject field , published inPhysics Letters B , it may be possible to tell apart which model is right by accurately appraise the amphetamine of solemnity .
Now , gravitation is think to be affect at the speed of light . Indirect measuring from galactic notice and direct measuring of gravitative waves seem to confirm this . The uncertainty on this measurement is tiny , but every new detection from the Laser Interferometer Gravitational - Wave Observatory ( LIGO ) will help fine-tune this time value .
If the value is found to be dissimilar from the speed of light , it would have in mind that our current reason of the universe is not correct and we might necessitate a different theory of gravity .
" Recent unmediated gravitational wave detection has spread out up a raw observational window to our Universe , ” Dr Lombriser pronounce in astatement . “ Our results give an imprint of how this will channelize us in resolve one of the most underlying trouble in physics . "
harmonize to the leading theory , known as the standard cosmological model , the universe is prevail by dark matter and dark energy , which is described by Einstein ’s relativity .. This is not just guess . The standard model pair the observance unbelievably well , but despite X - long studies , we still do n’t fuck what dark matter and disconsolate Energy Department is .
For this reason , several other scientists are investigating alternative ideas . These ideas are build purposely to avoid colored energy and dark matter , but they have not had the same achiever as the standard poser in explain the observations .
LIGO has recently undergonean upgradeand is currently scan the skies for hints of gravitational waves . Hopefully , many more detections will be bring to last year ’s , and if these research worker are correct , LIGO might save a all-important clue about the true nature of the universe of discourse .
